Enum VideoDecodeError 

pub enum VideoDecodeError {
    Decode(Error),
    Convert(ConvertError),
    PostCommitNeverResynced(PostCommitNeverResynced),
    FramePending,
}

Error type for [FfmpegVideoStreamDecoder].

Variants

Decode(Error)

The wrapped decoder (HW or SW) reported an error.

Convert(ConvertError)

Frame conversion from FFmpeg’s native types to mediadecode’s types failed.

PostCommitNeverResynced(PostCommitNeverResynced)

A post-commit HW->SW fallback degraded the stream but the software decoder reached EOF without ever producing a frame.

FramePending

A decoded frame is parked, waiting for a conversion that can commit, and nothing may be sent until it has been delivered.

The answer is VideoStreamDecoder::receive_frame: it re-attempts the parked frame. A caller who would rather abandon it calls flush, which clears the seat with the rest of the decoder’s position.
